Sometimes, on Mac OS X, programmers accidentally press Option+Space
rather than just Space and don’t see the difference. The problem is
that Option+Space writes a non-breaking space (0XA0) rather than a
normal space (0x20).
This commit removes all the non-breaking spaces inadvertently
introduced in the comments of the code.
Makes String#mb_chars on Ruby 1.9 return an instance of ActiveSupport::Multibyte::Chars to work around 1.9's lack of Unicode case folding.
Refactors class methods from ActiveSupport::Multibyte::Chars into new Unicode module, adding other related functionality for consistency.

blindly trust that all strings are properly encoded. With these methods
you can check incoming strings and clean them up if necessary.
